Home Phoneline Networking Alliance (HomePNA) 2.0 기술은 기존의 댁내 전화 선로를 이용하여 홈 네트워크를 구축하는 기술로서, 4-32 Mbps의 고속 데이터 전송 속도를 제공한다. 이러한 HomePNA 2.0의 Medium Access Control(MAC) 프로토콜은 IEEE 802.3 Carrier Sense Multiple Access with Collision Detection (CSMA/CD) 방식을 사용하면서, Quality of Service(QoS) 알고리즘을 제공하구 충돌 해결 알고리즘은 Distributed Fair Priority Queuing(DFPQ) 알고리즘을 사용한다. 본 논문은 HomePNA 2.0 MAC 프로토콜 성능의 중요 요소인 포화 처리율(Saturation Throughput), 패킷 지연(Packet Delay) 및 패킷 지터(Packet Jitter)에 대한 수학적인 모델을 제안하고, 이에 대한 모의 실험(Simulation) 결과를 제공하며, 각각의 모의 실험 결과를 분석함으로써, HomePNA 2.0 MAC 프로토콜의 성능을 종합적으로 분석한다.
